Faulty banner repeater

I agree that they probably don't know the ins and outs but they should know terminology like repeater, banner repeater, distant signal etc.

Why would they need to know all that? To be honest, all they need to be told is signal failure and the ID of the signal. Whether it's a distant, banner, home, starter, section or repeater makes no difference to them.

In any case, as stated above, it would probably have been reported already as it is a very noticeable fault.

There are banner repeaters used instead of "OFF" indicators in many places. Marylebone and Paddington in London both have this type of installation.

Where they are provided in platforms, they tend to remain clear until the signal has been replaced to danger so that they can be used by staff rather than having to provide separate "OFF" indicators as well.

This does have the potential to cause delay - drivers will slow down if they think a signal is against them, and station staff will not try and despatch a train which does not appear to have the road, even if in reality it does.

However, as has already been said.

Modern practice is for the banner to replace to danger as soon as the train passes. Therefore Banner On and Signal Off is not a failure when there is a train sat in between them.

Wherever reasonably practicable, and under all circumstances where permissive
working is authorised, a distant or banner repeating signal should be replaced by a
train detection device situated between itself and its first related stop signal. An
exception is made in the case of a banner repeating signal in a terminal platform,
where it is generally more informative for it to reflect the state of the platform
starting signal.

All types of banner repeater may be platform mounted and therefore used for train dispatch purposes although this may require delayed replacement of the banner such that it acts as an OFF indicator.
For terminal platforms, miniature banner repeaters may be used.

Also found one at St. Pancras Low Level station: a mid-platform banner repeater will replace itself if the track between it and the signal at the end of the platform is occupied. Not sure whether this is actually installed yet.

Geoff, assuming you mean St Pancras International the Banner is high above the track and out of sight of the platform staff when there's a train in the platform. I believe separate OFF indicators are provided.

It is commissioned, I did some of the testing!

I wasn't aware, at the time, that some Banner Repeaters revert once the train has passed them and not the signal relating to them, but perhaps obviously I do now. Quite surprised if this is the case at Cross, since the trains (the one in this case was a HST) can't really pass them, per se, if they're starting in a terminating platform.
